A friendly duel and deadly combat were essentially the same thing, only with one important difference - in a friendly duel, no one was going to kill their opponent.
Oren had informed Valira of this, he had properly warned her not to accidentally kill her opponent. After all, she was a mage and her opponent a knight, so the outcome of the duel was obvious to everyone.
However, the situation turned out in a way no one expected.
Valira took the loser's position, while Evan was obviously winning, but that was the least of the problems.
Halvor, Klaus, Oren, and Alf realized through experience that Evan was absolutely serious about his desire to kill Valira.
His gaze was cold, and his rapier covered in flames, was quickly coming down on Valira. She had no chance to dodge because Evan was too close, and she couldn't defend herself, because even among her spells there was nothing suitable.
Whoooooooooooosh.
